README suggestion

I'd love if https://github.com/pyoner/svelte-typescript/tree/master/packages/preprocess could describe what it does. It takes a .svelte file and outputs a .ts, .tsx, and .css file?

Another thing that would be useful is a comparison to other packages. E.g. what's the difference between this and https://github.com/kaisermann/svelte-preprocess?

@benmccann thank you for the suggestion!
I'll add a description and comparison

And sooo.... Any difference with @kaisermann's one ?

[kaisermann]

If I'm not mistaken, right now both preprocessors work similarly, with a difference of implementation here or there. However, in v4 of svelte-preprocess we're going to remove type-checking from the preprocessor and leave it to svelte-check and other language tools.
